My Mother adopted a Year -old-Siamese cat today,how do we properly introduce it to her Dog?

One don't rush anything. The cat has to get use to its surroundings first. You can't just take an animal and mix them together. If that dog has had the run of the house take it easy, and let him get use to the idea of another animal being in the house.

A one year old cat is probably still going to be playful and might not mix well first.

some breeds of dogs are not good with cats - you should have made yourselves aware of how your dog would react to a cat before getting one..

also a cat who is okay with dogs will not react - a cat who hisses or runs will become a target..

so - yes keep the cat in a room to itself for a few days (you should always do this with a new pet anyhow)

in the mean time work with reminding the dog of any training it has had.. eg. Sit, Stay, Leave it. so that when you do let the cat out you can keep the dogs attention on YOU - not the cat.. use lots of soft treat rewards and if you are concerned - but the dog on a leash.

BAD breeds towards cats are - Huskies, any sight Hounds, some Terriers..

good luck... go slow...

there is no proper way to intorduce a cat to a dog and i will be the first ont to tell you that. it will come a natural insteink to the cat and to the dog. see my cat and my dog get along fine but my moms cat and my dog hate eachother. it will just come naturaly.

ps. simese cats are not always known as a friendly cat.

In your dog's food bowl.
